摘要:
The Central California Coastal Circulation Study (CCCCS) was an 18‐month field program designed to study the variability of water mass characteristics and the velocity field on the continental shelf and upper continental slope of California from Point Conception to San Francisco. This study was funded by the U.S. Department of Interior, Minerals Management Service (MMS), as part of an overall assessment of the impact of development of oil and gas resources on the ecosystem of coastal California. The Santa Maria Basin area, which extends from Point Conception to Point Buchon (100 km to the north) and about 50 km offshore, is of particular interest, as this area will be the focus of oil and gas exploration and production over the next decade. However, MMS is also interested in how the ocean variability in this region relates to the large‐scale flow of the California Current System. The field work for CCCCS was conducted from February 1984 through July 1985 by Raytheon Service Company. This paper summarizes some of the preliminary results from analysis of the CCCCS d

摘要:
One of the classical oceanographic problems that the World Ocean Circulation Experiment (WOCE) will be able to address concerns the formation mechanisms of the oceans' dominant water masses and their subsequent spread thoughout the world's oceans. The formation sites for water mass end members are often mediterranean (or partly enclosed) seas where distinct water mass property characteristics are efficiently produced because of the relatively small volumes of these seas and because of their restricted communication with the ocean interior. The distributions of individual marginal sea water mass characteristics in ocean interiors have proven to be valuable diagnostics for the general circulation. Despite the variety of water mass formation sites on the globe, there exists a strong commonality in the world ocean water mass characteristics. The relative homogeneity is attributable to the active interchange of waters between the oceans. Such interbasin exchange may be thought of as the global adjustment of the oceans to differential thermohaline forcing.

摘要:
The Great Lakes area, the East Coast, and the southern rim of the United States may experience relatively stormy, wet weather this winter, according to the winter weather forecast for the continental United States from the National Oceanic and Atmospheric Administration's National Weather Service (NWS; see Figure 1). The NWS statement, which predicted average conditions in December, January , and February, also said that the south central portion of the United States has the highest chance of colder than normal winter weather, while the season is expected to bring milder than normal conditions west of the Rockies (Figure 2).The precipitation prediction is the “more interesting, stronger” part of the forecast, according to Donald L. Gilman, chief of the NWS Prediction Branch. This winter's temperature predictions are more cautious than usual, he s

摘要:
In anticipation of the start (in Fiscal Year 1988) of a new Office of Naval Research (ONR) Accelerated Research Initiative (ARI) on Ocean Surface Wave Dynamics, a workshop was held August 5–7, 1986, at Woods Hole, Mass., to discuss new ideas and directions of research. This new ARI on Ocean Surface Wave Dynamics is a 5‐year effort that is organized by the ONR Physical Oceanography Program in cooperation with the ONR Fluid Mechanics Program and the Physical Oceanography Branch at the Naval Ocean Research and Development Activity (NORDA). The central theme is improvement of our understanding of the basic physics and dynamics of surface wave phenomena, with emphasis on the following areas:precise air‐sea coupling mechanisms,dynamics of nonlinear wave‐wave interaction under realistic environmental conditions,wave breaking and dissipation of energy,interaction between surface waves and upper ocean boundary layer dynamics, andsurface statistical and boundary layer coherent str

摘要:
George Backus has made important, original contributions to mathematical geophysics over the last 30 years. In his doctoral research, under S. Chandrasekhar, he extended Cowling's theorem to show that an axisymmetric magnetic field could not be sustained in a sphere of conducting fluid with time‐dependent axisymmetric flow. In 1957, Backus and A. Herzenberg independently demonstrated that Elsasser had been correct in suggesting that dynamo action in a fluid sphere was possible if the axisymmetry were broken. This result forms part of the foundation of geomagnetic dynamo theory and still depends on the mathematical demonstration due to Herzenberg and Backus, as experimental tests remain inconclusiv
